Creating Multiple Metadata Files
As mentioned earlier, you can create multiple metadata files in order to provide multiple datasets to users.
As shown in the example above, the WMB is capable of inserting multiple child Metadata elements beneath a single Connection element. Multiple Connection elements, each with their own child Metadata elements, can also be added. The result, in the Active Query Builder, is a combined list of datasets for the user to select for analysis.
For information about using metadata with the Active Query Builder, see The Analysis Grid for Developers.
